L'Oréal Professionnel Keratin Alpha Sleek Professional Sulfate-Free Shampoo 300ml

L'Oréal Professionnel Keratin Alpha Sleek Professional Sulfate-Free Shampoo 300ml is a professional smoothing shampoo designed for long-lasting smoothness, frizz control and volume control.

Its luxurious, ultra-creamy formula gently cleanses the hair without sulfated surfactants while helping smooth and reinforce the hair fibre. It leaves hair feeling softer, more hydrated and easier to manage while delivering instant shine.

Powered by Keratin-Alpha Shaper and Amino-Acid Chains, the shampoo forms the first step of the professional Keratin Alpha Sleek routine, developed for customers who want smoother, softer, more controlled hair with easier everyday styling.

Cleanse → Smooth → Hydrate → Control Frizz → Enhance Shine

What Is It?

Keratin Alpha Sleek Professional Sulfate-Free Shampoo is the cleansing step within L'Oréal Professionnel's Keratin Alpha Sleek anti-frizz and smoothing system.

Unlike a conventional smoothing shampoo that primarily conditions the surface of the hair, the Alpha Sleek system is designed around technology that works with the hair's Keratin Alpha structure.

The shampoo gently cleanses while helping:

Smooth the hair fibre
Control frizz
Control unwanted volume
Improve softness
Maintain hydration
Increase shine

It is suitable for all hair types.
